What are the best niches for affiliate marketing today?

From my experience, niches that work today are:1. Fitness and supplements (people always want to lose weight).2. Software and digital tools (recurring commissions).3. Personal finance (credit cards, loans, insurance).4. Pet products (growing industry).Affiliate marketing works best when passion + demand meet. If you like tech, promote gadgets. If you like cooking, promote kitchen tools.

Health, wealth, and relationships are always evergreen. In 2025, AI tools, crypto, eco-friendly products, and online education are booming niches for affiliate marketing. But don’t just chase the trend; pick what you understand.
